Best Answer: Because cancer is not a single disease. That is the first problem. The second is that any cancer changes over time; therefore, no cancer remains the same. These are two of the reasons why treating cancer is so difficult. There is not one disease so no cure fits all. Even in the same person a cancer changes over time so an early treatment may become less effective as the cancer develops.

They work against some cancers with varying results.
Keep in mind that all cancers are different.
It is easy to say something like "breast cancer" but 5here are more than 17 DIFFERENT types of breast cancer alone.

There are thousands of different types & causes of cancer, so a cure or prevention for one specific type may be totally irrelevant to other types - a bit like having had a polio vaccination stops that, but not any other viral disease.
